目的总结肾盂输尿管移行细胞癌的64排螺旋CT表现特点,以提高对该病的诊断正确率。方法对27例临床确诊的肾盂输尿管移行细胞癌患者的64排螺旋CT(MSCT)资料进行回顾性分析。所有病例都包含了常规的平扫以及肾皮质期、肾实质期和排泄期三期的增强扫描资料,并利用AW4.5工作站进行各种后处理。结果术前通过64排CT扫描对25例肾盂输尿管移行细胞癌的患者做出了正确的诊断,准确率高达92.6%。64排螺旋CT能够清晰显示肿瘤侵犯的位置、范围、数目及输尿管壁的增厚和向外侵犯的情况。结论 64排螺旋CT及其后处理技术对于输尿管移行细胞癌的诊断具有极高的应用价值。
Objective To summarize the features of 64-slice spiral CT in renal pelvis and ureter transitional cell carcinoma to improve the diagnostic accuracy of the disease. Methods The data of 64 spiral CT (MSCT) in 27 cases of clinically diagnosed renal pelvis and ureter transitional cell carcinoma were analyzed retrospectively. All cases included routine scan and enhanced scan data of the renal cortex, renal parenchyma, and excretory phase and were post-processed using the AW4.5 workstation. Results The correct diagnosis of 25 patients with renal pelvis and ureter transitional cell carcinoma was performed preoperatively with 64-slice CT scan, with an accuracy of 92.6%. 64-slice spiral CT can clearly show the location of tumor invasion, the scope and number of ureteral wall thickening and outward violations. Conclusion 64-slice spiral CT and its post-processing techniques for the diagnosis of ureteral transitional cell carcinoma has a very high value.
